Furthermore THERP is not restricted to the assessment of designs already in place and due to the level of detail in the analysis it can be specifically tailored to the requirements of a particular assessment. [3] THERP is compatible with Probabilistic Risk Assessments (PRA); the methodology of the technique means that it can be readily integrated with fault tree reliability methodologies. [3] The THERP process is transparent, structured and provides a logical review of the human factors considered in a risk assessment; this allows the results to be examined in a straightforward manner and assumptions to be challenged. [3] The technique can be utilised within a wide range of differing human reliability domains and has a high degree of face validity. [3] It is a unique methodology in the way that it highlights error recovery and it also quantitatively models a dependency relation between the various actions or errors.
